Yes, it is possible to teach a Bengal cat to walk on a leash. However, it is important to keep in mind that cats are not natural leash walkers and may require a bit of extra training and patience. Here are a few tips to help you get started:

1. Start by getting your cat used to wearing a harness. You can do this by leaving the harness on your cat while they are indoors and allowing them to get used to the feeling of it.
2. Once your cat is comfortable wearing a harness, attach a leash and let your cat drag it around the house. This will help them get used to the feeling of the leash.
3. Gradually increase the length of the leash as your cat becomes more comfortable.
4. When your cat is comfortable dragging the leash around the house, take them outside for a walk. Start with short walks in a familiar, enclosed area and gradually increase the length of the walks as your cat becomes more comfortable.
5. Be patient and don’t try to force your cat to walk if they are not ready. Cats may need more time to adjust to the leash, so be prepared to take things slowly.

With patience and consistent training, it is possible to teach your Bengal cat to walk on a leash.
